SPRING SUSPENSION.

Application filed March 3,

To a l whom it may concern Be it known that I, GEORGE F. VoIon'r, a citizen of the United States, residin .at San Francisco, in the county of San Bram cis *0 and State of California, have invented new and useful Improvements in Spring Suspensions, of which the following is a specification.

My invention relates to spring suspensions adapted to be applied to automobiles of the Ford type of construction. 1

An object of my invention is to provide yieldinv means adapted to be interposed hetwecn the ends of the vehicles leaf springs and its axles, embodying primary and secondary levers working in conjunction with coil springs, for assisting the leaf springs in cushioning the vehicle against the nnevenness of the road over which it may travel.

With the foregoing and other objects and purposes in view winch description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention can be made within the scope of what is claimed'with-. out departing from the spirit of the invention.

In the drawings:

v Figure 1 is a portion of the front end of an autorxiobile with a unit of my invention applied to the left hand side thereof.

Fig. 2 is a sectional elevation of the device, showing also portions of the vehicle.

Fig. 3 is a plan view of a portion of the invention, portions being shown in section.

Fig. 4 is a plan view, with portions shown in section, of another portion of the invention.

Fig. 5 is a plan view of a portion of the devire.

Fig. '6 is a sectional view on line a--a., Fig. 2.

To facilitate in designating the relative positions of the various parts and members of the present invention, the term inner cud or its synonyms, will indicate the end nearest to the median vertical plane extending longitudinallythrough the vehicle, and the term outer end or its equivalents, will indicate the cud farthest away from said plane.

will appear'as the Specification of Letters Patent. Patented J 14 1921 191.9. Serial No. 220,214.

Like numerals of reference indicate likeparts throughout the several views.

1 designates the front axle of a vehicle, supported at one end by a wheel 2, and support n intermediate its ends a rigidly secured )rackct 3 rotatably supporting a pivot pin 4 to which is attached the outer bifurcated end of a primary lever 5.

its the front leaf spring of the vehicle, which overhangs the axle 1 and extends in a general direition therewith.

7 designates a channel member disposed above the spring 6 and has a cap plate 8 rilg idy clamped thereon by means of spring c l lpon the channel member 7, intermediate its outer end and the cap 8, is seated a saddle plate 1), which rotatahly sup )orts at its outer end a pivot pin 11, to the rec ends of which are attached the upper ends of a pair of links 12. The inner end of the saddle plate may be secured to the clip 9.

1:1 designates a secondary lever having its inner end forked, thereby forming a pair of arms let disposed one on oath side of the leaf spring 6 and free to move relatively thereto, the free ends of the arms being pivot-ally attached to a pivot pin 15 sup- )ortcd by the lower ends of the links 12. t is intended that the links 12 shall be oscillatable relatively to the arms 14 as well as to the saddle plate 10.

16 are the side links of a spring shackle, which have their upper ends pivotally attached to the outer end of tlei lever 13 as at 17, by means of a shackle pin 18, and

their lower ends pivetall v attached to the outer end of the leaf spring 6 by means of a shackle pin,19.

21) represents a pair of laterally spaced apart arms, which form the inner bifurcated end of the priu'iary lever The-free ends of said arms being disposed one on titt'll side of the lever 13 iutcrmcdiate'its ends. and pivotaliy attached thereto by and extends upwardly through the opening 23, through the longitudinalopening of the coil spring 24-, and through the opening 26, and is threadeclly engaged above the cap 25 by a nut 28.

On one side of the stem 27 are a pair of spaced apart projections 29 projection 29 1s engageable with the lower side and the projection 30 with the upper side, of the primary lever 5 at 31, for limiting the upward and downward movements of the stem 27 relatively to the lever 5.

From the foregoing it can be seen that the outer end of the primary lever is pivotally supported by'the axle of the vehicle, and that the inner end of the secondary lever is relatively movably supported by a portion of the vehicle frame, that the inner end of the primary lever is pivotally supported by an intermediate portion of the secondary lever and is movable relatively to its outer support, and that the outer end'of the scc ondary lever is yieldingly supported relative to the primary lever by'the coil spring, and that said arrangement may yicldingly form a support for the outer end of the leaf spring.

lVhile I have shown, in the drawings, my invention as applied to the left hand side of the front end of an automobile, it is to be understood that it is applicable to the right hand as well as to the left hand side, and to the rear as well as to the front end of any machine.
